Description

Technical Field

[0001] This invention relates to the field of material hoisting, and more specifically to a material hoisting correction and anti-falling winch. Background Technology

[0002] In numerous fields such as construction, mining, and port logistics, vertical and inclined material lifting operations are core components of the production process. As a key piece of equipment for material lifting, the winch's operational stability and safety directly determine operational efficiency, personnel safety, and the risk of property damage. With the expansion of industrial production scale, the amount of material lifted is constantly increasing, the lifting height is continuously rising, and the operating environment is becoming increasingly complex. This places more stringent demands on the winch's operational accuracy and safety protection capabilities.

[0003] During material hoisting, the misalignment of the winch wire rope or the tilting of the hoisting platform (such as a cage or bucket) is a common problem. Causes include uneven tension on the wire rope, insufficient drum machining precision, wear on the guide mechanism, load eccentricity, and environmental interference (such as wind and ground subsidence). If the misalignment cannot be corrected promptly and accurately, it will not only lead to abnormal friction between the wire rope and the drum and guide wheels, accelerating equipment wear and shortening its service life, but may also cause the wire rope to jump off the groove, become entangled, or even cause serious safety accidents such as the hoisting platform colliding with the track or overturning. Furthermore, when the wire rope falls off the winch, it cannot be properly handled, easily leading to safety accidents. This also results in poor applicability and an inability to meet actual usage requirements.

[0004] Therefore, there is a need to provide a material hoisting correction and anti-falling winch, which aims to solve the above problems. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0031] See Figures 1 to 7A material hoisting correction and anti-falling winch includes a winch base 3, which is installed on one side of a support frame 1. A steel wire rope 6 for winding is provided on the winch base 3, and one end of the steel wire rope 6 is connected to a cage 2. The winch also includes: An anti-derailment winch mechanism is installed on the winch base 3 and is used to drive the winch to operate and to prevent derailment. The anti-derailment winch mechanism includes a cable bundle plate 9 for cable management. The cable bundle plate 9 is slidably connected to the winch base 3, and a limiting plate 13 for anti-derailment limiting is provided at the joint between the wire rope 6 and the cable bundle plate 9. The limiting plate 13 is slidably connected to the inside of the cable bundle plate 9.

[0032] Furthermore, one end of the wire rope 6 is fixedly connected to a hook 16, which is lifted and installed on the lifting seat 17. The wire rope 6 is driven and connected to the first guide wheel 14 and the second guide wheel 15. The first guide wheel 14 and the second guide wheel 15 are fixedly installed on the support frame 1. The other end of the wire rope 6 is limited and installed on the winch roller 4.

[0033] Furthermore, the anti-derailment winch mechanism also includes a winch motor 5 for driving the winch roller 4 to wind and connect. The winch roller 4 is rotatably mounted on the winch base 3, and the output shaft of the winch motor 5 is fixedly connected to the winch roller 4.

[0034] Furthermore, the anti-detachment winch mechanism also includes a reciprocating screw 8 for driving the cable tray 9 to move the cable management mechanism. The reciprocating screw 8 is rotatably mounted on the winch base 3. The reciprocating screw 8 is rotatably connected to the winch roller 4 via a synchronous belt 7. The cable tray 9 is threadedly connected to the reciprocating screw 8, and the cable tray 9 is slidably connected to the winch base 3 via a first slider 10. The cable tray 9 has cable management holes 11 that are suitable for connecting the wire rope 6.

[0035] Furthermore, the anti-detachment winch mechanism also includes a first electric push rod 12 for driving the limiting plate 13 to perform anti-detachment movement control. The limiting plate 13 is fixedly connected to the piston rod of the first electric push rod 12, and the limiting plate 13 is located near the cable tie hole 11. The first electric push rod 12 is fixedly installed inside the cable tie plate 9.

[0036] Preferably, when lifting materials in the cage 2, the wire rope 6 is lifted and connected to the lifting seat 17 via the hook 16. Then, the wire rope 6 is transmitted through the second guide wheel 15 and the first guide wheel 14 on the support frame 1, and then tied and wound around the winch roller 4. During lifting, the winch motor 5 controls the winch roller 4 to rotate in both directions, thereby realizing the lifting operation of the cage 2.

[0037] To ensure proper winding of the winch roller 4, the reciprocating screw 8 is driven to rotate simultaneously by the synchronous belt 7. At this time, the wire harness plate 9 moves back and forth under the threaded connection with the reciprocating screw 8 and the limiting and guiding action of the first slider 10, which facilitates the even release and winding of the wire rope 6 onto the winch roller 4. When the connection between the wire rope 6 and the winch roller 4 falls off, the first electric push rod 12 drives the limiting plate 13 to move closer to the wire harness hole 11, thereby completing the limiting treatment of the wire rope 6 by the limiting plate 13, preventing the wire rope 6 from falling off and improving the safety of use.

[0038] It should be noted that the output shaft of the winch motor 5 can be driven in both forward and reverse directions.

[0039] By using this technology of uniformly winding and releasing the wire rope, wear on the wire rope is effectively reduced, the service life of the core components is extended, and the stability during the lifting process and the safety of material conveying are improved. At the same time, it improves operating efficiency, reduces downtime for adjustment, and can automatically limit the wire rope when it falls off, thereby ensuring personnel safety and improving the safety of the working environment.

[0040] like Figures 1-10 As shown, this embodiment, based on the above embodiment, also includes a correction mechanism, which is installed at the connection between the cage 2 and the wire rope 6, and is used to correct the position of the cage 2. The correction mechanism includes a lifting plate 21 for correction docking. One side of the lifting plate 21 is connected to a first traction rope 18 for lateral correction, and the other side of the lifting plate 21 is connected to a second traction rope 29 for vertical correction. One end of the second traction rope 29 is pulled and hooked to a fixing ring 27 by a spring hook 28. The fixing ring 27 is fixedly installed on the lifting plate 21.

[0041] Furthermore, the correction mechanism also includes a fourth guide wheel 30 and a third electric push rod 31 for correcting the traction of the second traction rope 29. The second traction rope 29 is drivenly connected to the fourth guide wheel 30, and the other end of the second traction rope 29 is fixedly connected to the cage 2. The fourth guide wheel 30 is rotatably mounted on the piston rod of the third electric push rod 31, and the third electric push rod 31 is limited to move within the lifting plate 21.

[0042] Furthermore, the correction mechanism also includes a second motor 35 for linearly adjusting the position of the third electric push rod 31. The third electric push rod 31 is fixedly mounted on the third slider 32. The third slider 32 is slidably connected to the inside of the lifting plate 21 by a guide rod 33. The third slider 32 is threadedly connected to the second lead screw 34. The second lead screw 34 is rotatably mounted inside the lifting plate 21. The second lead screw 34 is fixedly connected to the output shaft of the second motor 35. The second motor 35 is fixedly mounted inside the lifting plate 21.

[0043] Furthermore, the correction mechanism also includes a third guide wheel 19 and a second electric push rod 20 for correcting the traction of the first traction rope 18. One end of the first traction rope 18 is fixedly connected to the lifting seat 17, and the other end of the first traction rope 18 is fixedly connected to the lifting plate 21. The first traction rope 18 is drivenly connected to the third guide wheel 19, and the third guide wheel 19 is rotatably mounted on the piston rod of the second electric push rod 20. The second electric push rod 20 is limited to move on the lifting plate 21.

[0044] Furthermore, the correction mechanism also includes a first motor 25 for linearly adjusting the position of the second electric push rod 20. The second electric push rod 20 is fixedly mounted on the second slider 22. The second slider 22 is slidably connected to the inside of the lifting plate 21. The lifting plate 21 has a guide groove 23 that is adapted to slide and connect with the second slider 22. The second slider 22 is threadedly connected to the first lead screw 24. The first lead screw 24 is rotatably mounted inside the lifting plate 21. The first lead screw 24 is fixedly connected to the output shaft of the first motor 25. The first motor 25 is fixedly mounted inside the lifting plate 21 through a fixing plate 26.

[0045] Preferably, in this embodiment, due to the uneven weight of the material, when the cage 2 tilts vertically due to the material, the third electric push rod 31 drives the fourth guide wheel 30 to lift and lower to complete the corresponding lifting and pulling process. Then, according to the tilt angle, the output shaft of the second motor 35 drives the second lead screw 34 to rotate. Subsequently, under the guidance of the guide rod 33, the third slider 32 drives the fourth guide wheel 30 on the third electric push rod 31 to move and pull, thereby completing the correction of the tilt angle on that side, which facilitates subsequent lifting operations.

[0046] When the cage 2 tilts laterally due to the material, the second electric push rod 20 drives the third guide wheel 19 to lift and lower to complete the corresponding lifting and pulling process. Then, according to the tilt angle, the output shaft of the first motor 25 drives the first lead screw 24 to rotate. Subsequently, under the guidance of the second slider 22, the third guide wheel 19 on the second electric push rod 20 is driven to move and pull, thereby completing the correction of the tilt angle on that side, which facilitates subsequent lifting operations.

[0047] This technology, which allows for both vertical and horizontal adjustment, eliminates the risks of uneven vertical and horizontal loads, ensuring the safety of materials and personnel. It also prevents collisions between tracks, protects the cage and track structure, and balances the tension of the wire rope, extending the lifespan of core load-bearing components. No downtime adjustment is required during operation, significantly improving material lifting efficiency. The technology is easy to operate, reduces reliance on professional operators, and lowers personnel training costs.

[0048] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.
